Unmanned autonomous vehicle for displacing feed
First Claim
1. An unmanned autonomous vehicle for substantially sidewardly displacing feed lying on a floor, which vehicle is provided with:
- two wheels that are separately drivable by separate drives;
a distance determining device for determining a distance from the vehicle to a wall portion;
a torque difference adjusting device for adjusting the torque difference between the wheels;
a feed displacing arrangement for substantially sidewardly displacing feed, the feed displacing arrangement comprising a ring or disk rotatable about a substantially vertical axis for contacting the feed for displacing the feed sideways; and
a control unit for controlling the vehicle and moving it in a direction of travel by controlling at least one separate drive, the control unit being programmed to maintain a distance determined by the distance determining device to the wall portion, which distance is greater than or equal to a pre-adjusted minimum distance to the wall portion.

Abstract
An unmanned autonomous vehicle for displacing feed lying on a floor is provided with two wheels that are separately drivable, a distance determining device for determining the distance from the vehicle to a wall portion, an orientation determining device for determining the orientation of the center line of the vehicle relative to the wall portion, a torque difference determining device for determining the torque difference between the wheels, a control unit for controlling the vehicle and moving it in a direction of travel, and a feed displacing arrangement for displacing feed substantially sidewardly. The control unit may be programmed in such a way that during operation the vehicle will maintain a distance determined by the distance determining device to the wall portion, which distance is greater than or equal to a pre-adjusted minimum distance to the wall portion. During operation the center line of the vehicle may be maintained with an orientation determined by the orientation determining device relative to the wall portion, which orientation is at least almost equal to a pre-adjusted orientation. During operation the drivable wheels of the vehicle may show a torque difference determined by the torque difference determining device, which difference can then be maintained at a value smaller than or equal to a pre-adjusted maximum torque.

20. An unmanned autonomous vehicle for displacing feed lying on a floor, which vehicle is provided with:
-
a drive arrangement for moving the vehicle in a direction of travel wherein the drive arrangement controls a drive of at least one wheel; a position determining device for at least partially determining a relative position of the vehicle; a feed displacing arrangement for displacing feed, the feed displacing arrangement comprising a circular element comprising a ring or disk rotatable about a substantially vertical axis for contacting the feed whose outer circumference constitutes an outer circumference of the vehicle; and a control unit for controlling the vehicle.

21. A method for controlling an unmanned autonomous vehicle for displacing feed lying on a floor via a control unit, comprising:
-
determining a distance from the vehicle to a wall portion; controlling the vehicle via the control unit and moving it in a direction of travel by controlling a drive of at least one wheel of the vehicle, and maintaining a pre-adjusted distance to the wall portion; and displacing the feed sideways by contacting the feed with a circular element comprising a ring or disk rotatable about a substantially vertical axis around an outer circumference of the vehicle.
